We just released a comprehensive C course on the freeCodeCamp.org YouTube channel. This course, developed by Dr. Charles Severance (aka Dr. Chuck), is designed to help you understand computer architecture and low-level programming using the classic C programming language.

About the Course

In this comprehensive course, Dr. Chuck uses the classic book "The C Programming Language" by Brian Kernighan and Dennis Ritchie, often referred to as K&R, to guide you through the fundamentals of C. This book, first published in 1978, has been instrumental in shaping modern programming languages and provides a solid foundation for learning C.

Here are the sections in this course:

  • K&R 0: Historical Context: Understand the historical significance of C and its impact on computing.

  • From Python to C: Transition smoothly from Python to C, comparing and contrasting the two languages.

  • K&R 1: A Tutorial Introduction: Get an introduction to the basics of C programming.

  • K&R 2: Types, Operators, and Expressions: Learn about data types, operators, and expressions in C.

  • K&R 3: Control Flow: Explore control flow constructs like loops and conditionals.

  • K&R 4: Functions and Program Structure: Understand how to structure programs and write functions.

  • K&R 5: Pointers and Arrays: Dive deep into pointers and arrays, key concepts in C.

  • K&R 6: Structures: Learn about structures and their uses in C programming.

  • Object-Oriented Programming: Discover the underpinnings of object-oriented concepts in C-based languages.

  • Encapsulation and Abstraction: Improve your understanding of these critical programming principles.

  • Tree Maps and Hash Maps: Implement complex data structures.

  • Epilogue: Reflect on the journey and the evolution of programming languages.

In the Epilogue of this course, Dr. Chuck interviews Guido van Rossum, the creator of Python, providing unique insights into the development of modern programming languages and their relationship with C.
